<h3>Support for Unicode 3.2</h3>
<h3>Support for Unicode 4.0</h3>
<p>Unicode properties and algorithms have been upgraded to <a href=
"http://www.unicode.org/unicode/standard/versions/enumeratedversions.html#Unicode_3_2_0">
Unicode 3.2</a>, which includes the addition of more than 1000 new encoded
"http://www.unicode.org/versions/Unicode4.0.0/">
Unicode 4.0</a>, which includes the addition of 1226 new encoded
characters. The UCA (<a href="http://www.unicode.org/reports/tr10/">Unicode
Collation Algorithm</a>) table is updated to the current version 3.1.1,
with Unicode 3.2-based canonical closure. All Unicode properties (except
for those in Unihan.txt) are now <a href=
"http://oss.software.ibm.com/cvs/icu/~checkout~/icuhtml/design/ucd_icu.html">
Collation Algorithm</a>) table
is still at version 3.1.1, with Unicode 4-based canonical closure,
because UCA 4 is not available yet.
All Unicode properties (except for those in Unihan.txt) are now <a href=
"http://oss.software.ibm.com/icu/userguide/properties.html">
available via direct APIs, and most via UnicodeSet</a>.</p>
<p>Note that a Unicode update includes changes in algorithms.
For example, the default iterator for finding titlecasing positions has
changed from the titlecasing iterator to the word break iterator
according to the Unicode Standard.</p>
<p><a href="http://www.unicode.org/reports/tr15/#Corrigenda">Unicode 4 fixes 5 normalization bugs</a>,
which changes the decomposition and canonical equivalence of 5 characters.
ICU 2.6 normalization uses Unicode 4 data, therefore contains these bug fixes.</p>
<h3>Currency formatting</h3>
<p>Formatting of currency values has been improved in ICU 2.6 by allowing
the specification of any currency with any language-specific formatter.
The currency itself can be chosen independently of the display language,
but an appropriately localized string will be displayed for the currency
symbol. The display symbol data is not fully fleshed out.
See the API references for ucurr.h and NumberFormat.
<code>icu/source/samples/numfmt/</code> is updated to illustrate this
feature.</p>
<h3>XML resource bundles</h3>
<p>The ICU team had developed a custom XML format that matched
the capabilities of the binary data structure of ICU .res files.
This format was not known to be used and not optimal for
translation/localization.
ICU 2.6 supports the standard XLIFF format for product localization by
providing tools to convert between .xlf and ICU .txt files.
See the User Guide
<a href="http://oss.software.ibm.com/icu/userguide/localizing.html">Localizing with ICU</a>
chapter for details.
The previous, ICU-specific XML format has been withdrawn.</p>
<h3>Flexible data loading</h3>
<p>ICU 2.2 has an extended search path functionality, more flexible data
